Relay characteristics
Relay Rated load Maximum current Response time

Y4/Y5/Y6 5 A 250 VAC/30 VDC 5A 10 ms
A total of six relay outputs are provided. The optocoupler isolated ARM I/O signals
control the relay line package current. After the line package is energized, the
corresponding signal indicator becomes ON. The relay outputs do not have the
common ground.
The inductive load (relay, contactor, and motor) causes voltage peak after the current
is removed. A TVS is used for protection at the Y1/M1 to Y3/M3 contacts of the relay,
Y3/M3 correspondingly. In addition, XCOM on the high voltage detection terminal CN4
must be connected to the 110 V neutral line of the safety circuit. No absorption circuit
